Scalped Lady A....help

I bought a nice young trio at auction, the birds looked great, but by time i got home and got them out of the wooden box I noticed one of the hens was scalped!!!
Here are a few pic! What can I do to fix this quickly, and without harm to the bird!

I had a quail have the same thing happen, only it was much worse, the vertebrae were even showing!!! I figured he was done in for, and asked my husband to put him out of his misery, but he got home late, and since I have put him in an isolation cage, sprayed his head and neck with cut heal, a liquid wound spray, and gave him chick starter and added vit/electrolytes and duramycin to his water, I figured he would either be gone by morning or better. He even had lost an eye, and I was so concerned he was suffering. By the am he was eating and drinking, and has totally recovered. I will never put him in with the others again, and he now has a big classy cage to himself, a reward for surviving!!! He still has no feathers to his head, and it was about 2 weeks ago, but he was what I would call "healed" in 3 days. Not sure if this is of any help. Good luck, he is a very nice looking bird. Oh, just noticed, yours is a hen. Not sure why that would happen, that kinda stuff only happens to my males when they fight when there are too many boys and not enough girls.

If she did it to herself, don't worry about blinders for now. Keep her in a separate cage, but right next to the others if possible. Clean the wound and apply regular neosporin, or furizone cream. Make sure nothing lays eggs in the wound and she should heal up quickly. I've had it so bad that you could see the bottom mandible of the jaw and skull. Healed up fine, just a small scar and a facelift, hehe.
